Operator Control Panel and Display

Current Record Window

Keeps a log the events that resulted in the current mode of operation. Ignores transient conditions that have been resolved.

Use “page” (F1) and up / down arrow to read the events.

For a complete history log, refer to the Records tab of the Menu and Data Window. Refer to Table 23 for a complete list of supported status messages.

UPS messages

 

 

 

 

 

Message

 

 

Description / Suggested Action (if any)

Inverter Comm. Fail

 

Internal RS485 communication failure between monitor and inverter

Rectifier Comm. Fail

 

Internal RS485 communication failure between monitor and rectifier

 

 

 

 

 

 

 

The CAN communication between different UPSs within a parallel system fails.

Parallel Comm. Fail

 

1.Check if there are some UPSs not powered on in the parallel system. If so, power

 

on these UPSs and check if the alarm disappears.

 

 

 

 

 

 

2. Press Fault Clear push button.

 

 

 

Battery Overtemp.

 

The Battery temperature is over limit. Check the battery temperature and ventilation

 

 

 

Ambient Overtemp.

 

The Ambient temperature is over limit. Check the ventilation of UPS room.

Battery Fault

 

Battery detected faulty (Reserved)

Replace Battery

 

Battery test failed, Battery should be replaced.

 

 

 

 

 

 

 

Before the end of discharge, battery undervoltage pre-warning should occur. After

Battery Low Pre-warning

 

this pre-warning, battery should have the capacity for 3 minutes discharging with full

 

load. The time is user-configured from 3 to 60 minutes.

 

 

 

 

 

 

Shut down the load in time.

 

 

 

 

Battery End of Discharge

 

Inverter turned off due to low battery voltage. Check the utility failure and try to

 

recover it.

 

 

 

Mains Volt. Abnormal

 

Mains Voltage exceeds the upper or lower limit and results in rectifier shutdown.

 

Check the input line-to-neutral voltage amplitude of rectifier.

 

 

 

Mains Undervoltage

 

Mains Voltage is undervoltage with derated load.

 

Check the input line-to-line voltage amplitude of rectifier

 

 

 

Mains Freq. Abnormal

 

Mains frequency is out of limit range and results in rectifier shutdown.

 

Check the rectifier’s input voltage frequency

 

 

 

Rectifier Fault

 

Rectifier detected faulty. Rectifier shuts down. Battery discharges.

Rectifier Overtemp.

 

The temperature of heat sink is too high to keep the rectifier running.

 

The UPS can recover automatically. Check the environment and ventilation.

 

 

 

Batt. Contactor Fail

 

Battery contactor or circuit breaker not responding to control signals.

Batt. Charger Fault

 

The voltage of the battery charger is too high.

 

 

 

Control Power 1 Fail

 

UPS operates but Redundant Control Power is not available.

 

 

 

Mains Phase Reversed

 

AC Input phase sequence is reversed.

 

 

 

Rectifier Overcurrent

 

Rectifier is overloaded.

Soft Start Fail

 

Rectifier could not start due to low DC bus voltage
